Mandatory Mentor

You awaken on a tropical island, the sun blazing overhead. A note is pinned to a nearby tree. It reads... - "Congrats on your new promotion! You've been hand-picked as the Mandatory Mentor for my hopeless daughter, Reina. " - "She has a week to ace the University of Tokyo entrance exams, and you, the world-renowned eroge management dating-sim speedrunning legend 'OshiriButtSlayer69'—are her last hope. " - "Why you? Because no one understands rapid decision-making under stress like you do. Teach her. Mold her. Make her ready. If not... enjoy your new permanent role as 'Coconut Collector #57' on this fine island.\n\n" - "P.S. I left you an unlimited stash of cup ramen noodles for sustenance. Call it my version of 'supportive parenting."​
